Abstract (en)

[origin: US2006280924A1] Disclosed are structural materials including polymeric reinforcment fibers that can provide added strength and fracture toughness to the matrix. The polymeric reinforcement fibers are polypropylene-based monofilament fibers or tape fibers exhibiting extremely favorable mechanical characteristics for structural reinforcement including modulus greater than 12 MPa and elongation less than about 10%. The disclosed reinforced composite materials can exhibit desired average residual strength values with less total fiber loading necessary to attain the ARS values as compared to previously known polymer reinforced materials. Very high strength and fracture toughness can be attained in the disclosed composite materials.
